Feeder dikes to the Columbia River Basalt Group (CRBG) large igneous province provide a rare opportunity to examine magma transport through the shallow crust during flood basalt eruptions. Over 70% of the CRBG erupted fr ...

The Nanga Parbat-Haramosh massif (NPHM) is a north-south trending
structural and topographic high, which interrupts the east-west trend
of the Himalaya in northern Pakistan. Previously, the massif was
thought to be bo ...

The interaction of magma with continental crust at convergent margins is fundamental to
understanding if and how continents grow. Isotopic and elemental data constrain the
progressive stages of development of the magma ...

The Absaroka volcanic province is the largest of Eocene volcanic fields in the northern Cordillera of the western U.S., and consists of 25,000 km2 of lava flows, shallow intrusions, ash-flow tuffs and volcaniclastic depo ...

The climatic and tectonic framework of the St. Elias orogen makes it an excellent place to study the interactions between tectonic processes such as deformation and erosive processes, in particular glacial erosion. One t ...

The Upper Ojai Valley is a tectonic depression between
opposing reverse faults, Its northern border is formed
by the active, north-dipping San Cayetano fault with 6.0
km of dip-slip displacement in the Silverthread oi ...

The Juniper Ridge volcanic complex is located in the High Lava Plains Province of
southeastern Oregon, a wide zone of bimodal volcanism and faulting that marks the northern
limit of widespread Basin and Range-style fau ...

The Oregon Mountain area contains an ophiolitic assemblage of rocks which can he divided into two major zones on the basis of lithology: (1) spilite and diabase, with minor chert, and (2) plagiogranite, hornblende gabbro ...

Himalayan collision produced frontal and lateral
ramps and associated Pliocene to Quaternary tectonic
geomorphic features in the foreland fold-thrust belt of
northwestern Pakistan. The transpressional right-lateral

The Coyote Hills are located about 46 kilometers north-northwest
of Lakeview, Oregon, within the Basin and Range physiographic province.
These hills represent a complex volcanic center of bimodal
calc-alkaline igneous ...
